What is the standard to distinguish a person from a good person or a bad person?

The standards of measurement and judgment are different, and the boundaries between good people and bad people are different. For example, if a person violates the law according to legal standards, he is a bad person and will be punished by law; Judging by a certain moral standard, a person has not broken the law, but has done immoral things and hurt the interests or psychology of others. If a person keeps doing immoral things, he will get worse and worse, that is, a bad person; It is relatively easy to judge a person's quality in behavior, but it is more difficult to judge in thought, but people's behavior is dominated by thought, so thought is the key. For example, judging a person's quality by selfishness is not something that can be seen at the moment. As the saying goes, "the road is long and the horsepower is known, and people will see it for a long time." In fact, people's hearts are very complicated, so it is difficult to judge. Everyone will form their own concept of measuring quality in life experience. For example, you say that this person is very good, but in the eyes of another person, he is a bad person, that is, the standards for measuring good or bad are different, and the boundaries are naturally different. The best people should also achieve the state of selflessness and selflessness, which ordinary people can't do. Most people have selfishness and love, but the ratio of selfishness and love is very different. Everyone wants to be a good person, so people should take good care of themselves, learn to keep their conscience and make good use of it.
